Neighbor-joining tree and network based on amino acids in the PBR of DQB allotypes. (A) A neighbor-joining (NJ) tree was constructed by using the number of differences method. DQB sequences of the giant panda are used as outgroups. Only bootstrap values over 50% are shown in this figure. (B) Neighbor-Net network is also based on the sequences of NJ tree
